Answer 1

To cool something down, you need to remove energy from it by transferring heat to something else. There are different ways to do this, like by putting the object in contact with something cooler, blowing air over it, or allowing it to radiate heat to cooler surroundings. Refrigeration and air conditioning are also specialized methods of cooling that use a combination of these processes. So basically, cooling is the opposite of heating – you’re taking energy away instead of adding it.
